'The present inventionrelatesto an apparatus for the removal of/oil i. e. for the condensation of the products of lubrication, which is chiefly adapted to collectthe'particles of oil or grease which are drawn forward with certain gas streams, and particularly with the air 'delivered'by aircompressors. I g

The apparatus according. to the invention is chiefly. characterized by the fact that it acts at the same time, firstly to cool the volume of airin all parts and thus to properly separate the. minute drops I of 011 01" grease whose suspension in the air is fun thered by thehigh temperature to which it is heated when issuing from the compressor cylinders, and secondly to heat the collected oily liquid in order to restore to it,.at least partially, the fluidity which it has lost under the effect. of the high temperature of the delivery, this fluidity being required for the ready discharge of theliquid, with or without pressure; a 7 I An advantageous'method consists in c0oling the air from which the oil is to be removed, by circulatinglit in contact'with a sufiicient number ofthin baflledevices which are cooled by external'fianges, whilst the oily drops. thus deposited thereon are directed, by a suitableslope of the said baiiles, to the peripheral walls of the apparatus, or

onthe contrary,.to the central part, so that it will then stream down by gravity along the said peripheral walls or along a central tube; i 1 1 3 Another feature ofi'the invention consists in the construction ofthe apparatus by the use of annular elements or rings in a superposed arrangement,'whereby the operating capacity of the apparatus may be modified by simply increasing or diminishing. the number of such rings according to the degree of purifying to, be obtained.

Figs. 1 and 2 showvby. way of; example two respective embodiments of the invention, in axial section. 1 I v In Figure l the apparatus comprises a case 1 forminga base, upon which are piled bafiie rings in superposed position. .The, interior2 ofsaid case forms a-collecting cham 'ber for .theifatty. substances may be pipe-fittings are provided in the wall of the case 1 above the conduit 4. In the upper face of the base. part1 is an annular groove 10 for the insertion (with packing) of the ring C The. said ring has at the top an annular groove. for the insertion (with packing) of the second-ring C and soon. The last ring O carries in like manner a covefllclosingthe pile at the top.

The various rings and vthe Tcover are'held together in'a non-leaking'manner bya plurality of bolts B spaced around the periphery, outside the main body of the rings C,' and; passing through corresponding notches in the outerv flanges 12 of the said rin s. Each ring comprises-- an interal ba e rib 13 which is inclined from the axis.

A vertical jaxial tube 14. is mounted on a shoulder formed on'said conduitl l' around the hole 7 thereof, and itrises to=a point above thefbafiieqrib. 13 of the last ring .Cn, stopping atva certaindistance from the cover 11 r intermediate tapered sheet metaldis ks 15,

through which the tube l lipasses loosely,

.bafiies according tothe arrows; The .said

sheet metal disks 15 are pierced with holes 16 in a row surrounding the central tube '14:, so that the oil will drop upon. the tube 14.

The operation is as follows One of the orifices 5 or 6 is closed'by a screwplug 17, and one of the orifices 8 or 9 is closedv by a like plug 18. The; air, is supplied to the transverse conduit 4, flows in the tube 14, and then returns on azigzag-path around the baffles 13-15, then issuing through the orifice 9. A sheet metal'plate 19 secured to the lower baflle 15 directs the air to the her 2, whence it may be discharged through the emptying orifice 3 when the latter is The air will thus be entirelyand in all parts cooled by its circulation incontact.

with the cooling ribs 13, which facilitates the separation of the. oil. 1 On the contrary,

the oil deposited along the tube 14 is sub jected to the: heat of the airsupplied directlyby the compressor to this tube. The

collecting chamber 2 is heated by the transv'erse'conduit' ii which is supplied with hot air. Such heating will reduce the viscosity of the oily deposits, and will facilitate their expulsion by the action of the compressed air when the emptying orifice 3 is opened.

The construction shown in Fig. 2 differs from thepreceding, due to the fact that the air circulates inthe other direction, and that the ribs and intermediate bafiles 1 15 are not inclined downwardly towards the centre, but are. downwardly inclinedtowards the periphery. Thecentraltube' 14 is eliminated, but the base part-1 is the same asin- Figure S1. .Herein the two upper or1- 'fice s 89 of the case 1 are both closed by vrespectivescrew plugs 18-18. The air is supplied at 5 and it escapes from the transverse conduit 4 through. the hole 7, then rises-andlcirculates in a zigzag path around .the ribs 13 andthe intermediate baffles 1 5 (which are herein closed atthe middle), and finally issues through a hole 21 forme at the top ofthecover 11. i I Obviously, the holes are pierced, as shown at 20, .at the lower part of the annular; concave parts formed by the baffle ribs 13, and thus the oil will flow downwardly along the peripheral walls of the apparatus, descending: thence into the collecting chamber 2.

The arrangements anddetails of construction herein 1-described and represented are given solely by way of example, and are susceptible of all, desiredvariations without departing from the principle of the invention;
